我看到这个词很多“缩小”,我似乎从来没有选择一个“缩小”的脚本(即来自jQuery插件),但我想我应该。如果我是正确的Minified意味着从源代码中删除所有不必要的东西而不改变它的功能,那么为什么我们不仅仅有缩小的来源以及为什么要烦扰完整的版本?为什么要给人们选择?
YOLO
答案 0 :(得分:45)
当你进行调试时,拥有完整的源代码要容易得多。当它说所有内容都在第1行时(因为所有内容通常都缩写为一条长行),以及一条不可读的第1行就很难调试。
我使用完整的版本进行测试,然后我将所有内容缩小以进行部署。

缩小版很难理解和调试
答案 2 :(得分:4)
答案很简单,不需要进一步解释恕我直言,来自jquery网站
现在,相当自我解释:
答案 3 :(得分:1)
如果您想了解脚本的工作原理或扩展脚本,那么最好使用非缩小版本。
答案 4 :(得分:1)
人为难以阅读缩小的脚本,并且难以调试。对于像jQuery这样的Javascript库,能够在调试期间读取您正在使用的任何函数的源代码,以便更好地理解它是如何工作的。在生产环境中,您绝对应该使用缩小版本来加速数据传输。

哦不! jQuery中有一个错误。你必须找到并修复它。
这是您的错误消息,您可能发生的唯一提示:

我的猜测是,最初,编写JavaScript库的人将它们写成“完整版”,即内置注释和代码格式 - 因为如上所述,代码更容易以这种方式阅读。然而,编写JavaScript库的人也知道缩小版本将更轻量级且更友好。由于开发人员已经拥有“完整版”,为什么他/她不会提供缩小版本?
在这种情况下,提供“完整版”不需要任何额外的工作,因为它是原始版本。只要开发人员要提供缩小版本 - 他也可以提供用于制作缩小版本的完整版本。使用开源JS库,提供带有注释和代码格式的完整版本,使社区更容易弄清楚发生了什么。
那就是说我会建议你在生产环境中使用缩小版。优选地,通过CDN递送缩小版本。

简单来说,缩小版本用于生产,非小型版本用于开发调试目的。
特别是对于性能而言,缩小版本更好。您可以通过firebug net panel检查加载时间之间的差异

你可以使用PHP脚本动态缩小(并在需要时缓存/ gzip)你的js脚本。这是我大部分时间都在做的事情。
它具有缩小你的javascript而没有缺点的所有优点。 节省约70%(gzip + minify)传输的数据。
